Spark throws an error

Hi Iā€™m new to all this stuff :slight_smile:

I have downloaded spark_2_5_8.msi and after installing it I tried running it but it does not start and I get the following error in the log directory, which to me does not mean anything :frowning:

Any ideas as to why this happens?

solved :slight_smile:

I had installed a previous version and uninstalled it. Unfortunately even though the installer had removed it it left some folders in the c:\documents & settings\username\spark directory. Deleting this folder, rebooting and reinstalling did the trick :slight_smile:

Thkx to everyone
